Hello,
After building our installer with the enhanced UI enabled we encountered an issue where some of the properties we set in the user selection dialogs are not actually set at the end of the install. I have attached a small test project that can be used to reproduce the issue. When the enhanced UI is disabled the project should display the contents of the edit box at the end of the install. When the enhanced UI is enabled it displays a blank message box instead of the value entered at the beginning. Let me know if you have any questions.
Thanks,
Logan
